Bed Occupancy Sensors

We have recently made a sensor for care home residents that will minimise risks of injuries and falls by residents, particularly at night when they are sleeping and are more likely to fall off beds.

These wireless, non-wearable sensors operate using a Doppler radar that detects micro-movements of the human body such as a heartbeat or breathing. Doppler technology uses the frequency spectrum within mmWave, and in our case we are using a radar with a frequency of 60 Ghz. Importantly, mmWave frequencies are non-ionising. These frequencies are much lower than those used by mobile phones, which prevents their penetration into the human body. 

The frequency detected by the Doppler radar is used to measure velocity and the data is transmitted to the user interface. Care home personnel can then use the information displayed to monitor residents’ health and safety by assisting those whose movement is undetected. This helps overall healthcare management in healthcare facilities.

These devices will be wholly manufactured in-house by Sensor IT as we value creating sustainable and innovative solutions from the ground up. We intend to deploy them in the long run in public healthcare facilities.

Air Quality Monitoring

Sensor IT has developed a highly configurable, small-footprint platform in response to the harmful pollutants including Carbon Monoxide (CO), Carbon Dioxide (CO2) and Volatile Organic Compounds (VOC) present in indoor and outdoor atmospheres. Our COVID-19 Air Quality Monitor device has been customised to monitor the parameters required, based on the end client, application and use case. Examples of the parameters that can be configured include:

  • Pollutants or chemical components to be included into the monitor
  • Stand-alone or fully connected device, including what communication protocol to implement: wireless networks (WIFI), Cellular, IoT (NB-IoT®, LoRaWAN®, Sigfox®, etc)
  • Battery or mains electricity
  • Display information locally (through a fitted LCD display) or/and through a cloud-based dashboard

This was specifically developed with the pandemic in mind and chiefly monitors the concentrations of CO2 in the air within enclosed spaces to indicate when ventilation would be required in order to minimise viral transmissions. The device is fitted with a full-colour LCD screen that provides a visual indication of the values read. The device also captures other ambient parameters, such as air temperature and humidity and Volatile Organic Compounds (VOC).

Two versions of the product allow clients to choose from a fully connected device that sends the data using either a WIFI network or an IoT (LoRaWAN®) gateway to a cloud-based dashboard, or a standalone version that simply presents the data using the LCD display.

Wastewater Monitoring System

Sensor IT designed a Wastewater Management System based on IoT components to monitor the Mombasa sewer system. The sewer previously faced numerous challenges arising from prolonged use and overload. Our solutions improved the system’s overall efficiency by preventing overspills of water and sewer blockages.

The Wastewater Monitoring system included multiple endpoints to measure the wastewater flow in several locations and the development of a real-time dashboard to monitor this flow. The system’s deployment set a precedent for future enhancements and streamlining of wastewater treatment operations.

The system was sponsored and partially funded by Innovate UK and was named Maji Taka Tech. WASREB (Water Services Regulatory Board) indicated in their 2020 Impact Report that “Utility efficiency is key to attaining targets”, these targets being Sustainable Development Goal 6 and the National Vision of Kenya committing to the universal access of water and sanitation by 2030. As of 2019, Mombasa is ranked last out of the 12 “very large WSP utilities’. Chances of sufficient investment in the sewer system remain unlikely therefore it is crucial to improve pre-existing infrastructure to increase its efficiency.   

Pinewood Smart Homes

From November 2021, a village hall in Whitehill & Bordon will be converted into homes for the homeless as East Hampshire District Council plans to construct individual studios inside Pinewood Village Hall, on Rydal Close.

Sensor IT is part of the group of companies that will deliver on this unique and highly innovative initiative, overseeing the custom design, development, installation and integration of all sensors to be deployed as part of the project. These include:

  • Ambient temperature, humidity and pressure
  • Air quality
  • Noise
  • Structural health
  • Leak prevention and detection
  • PV panels performance and fault alert

The custom design incorporates several innovative features, such as:

  • Photovoltaic solar panels generate renewable and sustainable electricity for the benefit of residents
  • A sophisticated fire suppression system and alarm
  • Building sensors to monitor the health of the building fabric
  • CCTV to improve the safety, management and welfare of residents
  • Sedum roof – a plant that sits on a waterproof membrane and creates an attractive ‘living’ roof
